Kalangdoo Town Water Supply (T.W.S.) No. 1 well was drilled cable tool during February - May, 1977, and subsequently production tested. The unconfined Gambier Limestone aquifer was encountered between 5.5 and 86m, and was later cemented off down to 98m. The confined Knight Group sand aquifer was intersected between 102 and 117m, and screened 105-113m. The results of production testing indicate that discharges of up to 150QmVday are permissable on drawdown considerations alone, but that screen encrustation may result frcm high entry velocities. A second well is being put down adjacent to Kalangadoo T.W.S. No. 1, and gravel packing or additional screen length may minimize encrustation effects. Further discharge testing, to derive more reliable transmissivity values using the new well for observation purposes, is recommended. Water quality averages about 620 mg/1 in the confined aquifer, and is marginally higher in the Gambier Limestone. Both waters are relatively hard. Though substantial leakage between the two aquifers is likely during pumping, this would not have a significant effect on water quality.
